TECHNICAL FIELD

An embodiment of the present invention relates generally to a computing system, and more particularly to a system for resource management mechanism.

BACKGROUND

Modern consumer and industrial electronics, such as computing systems, servers, appliances, televisions, cellular phones, automobiles, satellites, and combination devices, are providing increasing levels of functionality to support modern life. While the performance requirements can differ between consumer products and enterprise or commercial products, there is a common need for more performance while reducing power consumption. Research and development in the existing technologies can take a myriad of different directions.

One such direction includes improvements in managing available resources. As the number of electronic devices and processing power of each device grows, the demand on computing resources is growing exponentially. Efficiently or effectively managing the available resources can provide the increased levels of performance and functionality across multiple devices.

Thus, a need still remains for a computing system with resource management mechanism for improved processing performance while reducing power consumption through increased efficiency. In view of the ever-increasing commercial competitive pressures, along with growing consumer expectations and the diminishing opportunities for meaningful product differentiation in the marketplace, it is increasingly critical that answers be found to these problems. Additionally, the need to reduce costs, improve efficiencies and performance, and meet competitive pressures adds an even greater urgency to the critical necessity for finding answers to these problems.

Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.

Satellite communication, cellular communication, Bluetooth™, Bluetooth™ Low Energy (BLE), wireless High-Definition Multimedia Interface (HDMI), ZigBee™, Near Field Communication (NFC), Infrared Data Association standard (IrDA), wireless fidelity (WiFi), and worldwide interoperability for microwave access (WiMAX) are examples of wireless communication that can be included in the network 104. Ethernet, HDMI, digital subscriber line (DSL), fiber to the home (FTTH), and plain old telephone service (POTS) are examples of wired communication that can be included in the network 104.

Further, the network 104 can traverse a number of network topologies and distances. For example, the network 104 can include a direct connection, personal area network (PAN), local area network (LAN), metropolitan area network (MAN), wide area network (WAN) or any combination thereof.

The network 104 can include one or more intermediate network component 108. The intermediate network component 108 can be between communication endpoints 110 generating and consuming a processing request 112. The intermediate network component 108 can include a device or a portion therein configured to relay information between the communication endpoints 110. For example, the intermediate network component 108 can include a router, a repeater, a base station, an amplifier, an interface within a device, or a combination thereof.

The communication endpoints 110 can include a device or a portion therein generating information. The communication endpoints 110 can include the device or the portion therein generating a request, generating a processing output, accessing information stored therein, or a combination thereof.

For example, one of the communication endpoints 110 can generate or produce the processing request 112 for accessing information. The processing request 112 can be communicated to another instance of the communication endpoints 110, and the other instance can generate or produce a processing result 114 as information or output corresponding to the processing request 112.

Also for example, the communication endpoints 110 can include a data provider 116 generating or producing the processing result 114. The data provider 116 is an instance of the communication endpoints 110 configured to process the processing request 112 and avail the requested information.

The data provider 116 can be a consumer for the processing request 112. The data provider 116 can process and respond to the processing request 112 without utilizing a separate device or a separate portion outside of the data provider 116. For example, the data provider 116 can be a storage device or storage portion within a device including the information requested by the processing request 112. Also for example, the data provider 116 can be the computing device or a calculation unit generating and directly providing the information requested by the processing result 114.

The computing system 100 can use the data provider 116 to implement a credit management mechanism 118 for the computing system 100. The credit management mechanism 118 is a method, a process, a circuitry, or a combination thereof configured to manage and balance expenditure of overall resources 120 for the data provider 116 in processing the processing request 112.

The credit management mechanism 118 can include a function, a digital circuit set, a step or an instruction, an equation, or a combination thereof predetermined by the computing system 100 to manage and balance the expenditure of the overall resources 120. The credit management mechanism 118 can further be configured to dynamically reconfigure itself, such as in adaptive or self-learning instances of the function, the circuitry, the step or instruction, the equation, or a combination thereof. The credit management mechanism 118 can manage and balance the expenditure of the overall resources 120 based on assigning credits or budgets for processing one or more instances of the processing request 112.

The overall resources 120 can represent a total processing capability of the data provider 116. For example, the overall resources 120 can represent an amount of data, a processing rate, or a combination thereof. As a more specific example, the overall resources 120 can include a data resource 122, a processing resource 124, or a combination thereof.

The data resource 122 can be a storage capacity. The data resource 122 can include volatile or non-volatile storage. The data resource 122 can include storage for latter access, the amount of data capable of simultaneous access at a given time or period, or a combination thereof.

The processing resource 124 can further represent a number of instructions or an amount of data that can be simultaneously processed for a given period.

The computing system 100 can use the credit management mechanism 118 to control, manage, divide, dedicate, expend, or a combination thereof for the overall resources 120 for processing one or more instances of the processing request 112. For example, the computing system 100 can prioritize pending instances of the processing request 112 including input/output (JO) read/write request using the credit management mechanism 118.

Continuing with the example, the computing system 100 can prioritize processing based on port, physical function, virtual function, or a combination thereof. The computing system 100 can use the credit management mechanism 118 for common data center environments where multiple computing hosts share the data provider 116 while observing Service Level Agreement (SLA) response time commitments. Details regarding the credit management mechanism 118 are discussed below.

The individual instances of the requesting host 316 from amongst all instances of the requesting host 316 connected to and supported by the data provider 116 can have significantly differing performance requirements that must be fulfilled to guarantee satisfying important SLA metrics. The data provider 116 can be expected to provide Quality of Service (QoS) measurements or performance parameters to each instance of the requesting host 316 according to the corresponding SLA.

For example, one or more instance of the requesting host 316 can require a high request fulfillment rate involving insignificant data transfer amounts or high bandwidth. Also for example, one or more instance of the requesting host 316 can present few requests that each require significant data transfer bandwidth. Also for example, one or more instance of the requesting host 316 can exhibit steady presentation request rates, each request requiring approximately uniform device-fulfillment response times. Also for example, one or more instance of the requesting host 316 can exhibit unpredictable bursts for request presentation rates.

The data provider 116 can utilize the credit management mechanism 118 to dynamically manage the various different needs and requirements across instances of the requesting host 316. The data provider 116 can enable the instances of the requesting host 316 to meet their specific mandated performance requirements despite other host request interference, or, in a worst case, allow hosts to fail their SLAs in a relatively graceful and balanced manner.

The data provider 116 can utilize the communication mechanism 310 which can be, for example, PCIe, including multi-function storage-device 304, and can expose a plurality of PCIe physical ports through a PCIe host interface.

The consumption prediction 418 can be based on an estimate of an upcoming or current instance of the processing request 112 from a corresponding instance of the requesting host 316 or other hosts. The consumption prediction 418 can further be based on remaining instructions or processing portions of the current instance of the processing request 112.

The prediction block 416 can calculate the consumption prediction 418 based on the host profile 318, the processing request 112, or a combination thereof. The prediction block 416 can calculate the consumption prediction 418 using the credit management mechanism 118, the dynamic budgeting mechanism 314, or a combination thereof.

It has been discovered that the budget, such as the instance budget 410 or the further budget 412, calculated at the data provider 116 provides improved response time. The budget can manage the conflicting demands across multiple hosts by metering and controlling the resource consumption with the budget. The reduction in conflicts and reduction in monopolization of the resource by one host over others can provide the improved response time.

It has further been discovered that the budgets calculated based on the host profile 318 for controlling the processing request 112 at the data provider 116 provides performance predictability. The budget calculated by the data provider 116 and implemented at the data provider 116 to control the usage of the overall resources 120 at the data provider 116 enables direct control based on real-time statuses. The control based on real-time direct status at the data provider 116 enables insight into usage and overall management unavailable at the requesting host 316 or the intermediate network component 108 of FIG. 1. The increased direct insight allows for predictable assessment and control over the resources, thereby providing predictability to the overall performance of the computing system 100.

The control flow can pass to the command fetch block 402. The command fetch block 402 can fetch the processing command based on the budget corresponding to the requesting host 316. The command fetch block 402 can further communicate the corresponding budget to the requesting host 316 for adjusting the processing request 112. The control flow can further pass to the command processing block 406. The control flow can pass similarly as described above between the command fetch block 402 and the credit checker block 404, but using the processing result of the credit checker block 404, such as the instance budget 410, the further budget 412, or a combination thereof.

The command processing block 406 is configured to process the processing request 112. The command processing block 406 can process the processing request 112 based on generating the processing result 114 of FIG. 1. The command processing block 406 can generate the processing result 114 corresponding to and in response to the processing request 112.

For example, the command processing block 406 can access the NAND subsystem of a storage device or the data provider 116. Also for example, the command processing block 406 can read from or write to a specific location within the data provider 116. Also for example, the command processing block 406 can detect data, process intermediate data, report data, or a combination thereof according to the processing request 112 and the capabilities of a given data provider 116.

The command processing block 406 can generate the processing result 114 according to the budget or credit associated with the corresponding instance of the requesting host 316. The command processing block 406 can further process the processing request 112 using one or more instances of the processing segment 312. The command processing block 406 can utilize up to or not exceeding an amount of resource designated according to the instance budget 410, the further budget 412, or a combination thereof.

The command processing block 406 can calculate a device access-credit 420, a further access-credit 422, or a combination thereof during the processing for generating the processing result 114. The device access-credit 420 and the further access-credit 422 can each represent resources or portions of the overall resources 120 spent or utilized for servicing the corresponding instance of the requesting host 316.

The device access-credit 420 can correspond to the utilization of processing segment 312. The command processing block 406 can reset the device access-credit 420 for each instance of the processing segment 312, such as at the beginning or end.

For example, the command processing block 406 can count the number of commands or instructions executed in tracking the processing resource 124 for processing the processing request 112 from a corresponding instance of the requesting host 316. Also for example, the command processing block 406 can measure the bandwidth or a transfer rate of data in tracking the data resource 122 for processing the processing request 112 from a corresponding instance of the requesting host 316.

The command processing block 406 can generate the processing result 114 based on the remaining or utilized credits not exceeding the budget corresponding to the requesting host 316. The command processing block 406 can stop the processing when the device access-credit 420, the further access-credit 422, or a combination thereof meets the instance budget 410, the further budget 412, or a combination thereof.

The command processing block 406 can generate the processing result 114 as the output of the process up to the stoppage point. The command processing block 406 can further set a credit exhaustion status 424 representing whether the balance has reached the end of the budget.

The command processing block 406 can communicate or pass the credit exhaustion status 424, the remaining number of amount of credits, or a combination thereof to the credit checker block 404, the command completion block 408, or a combination thereof. The credit checker block 404 can use the credit exhaustion status 424, the balance, or a combination thereof to calculate the consumption prediction 418 and adjust the instance budget 410, the further budget 412, or a combination thereof.

It has been discovered that the budget implemented with balance at the data provider 116 provides increased reliability and predictability. The data provider 116 can control the overall resources 120 in real-time with actual usage data reflected in the balance. The actual usage data at the data provider 116 can provide insight otherwise missing at the intermediate network component 108 or the requesting host 316 including the first device 102. The control based on the balance and the budget can reduce conflicts across multiple hosts, thereby increasing reliability and predictability for the computing system 100.

The control flow can pass from the command processing block 406 to the command completion block 408. The control flow can pass similarly as described above between the command fetch block 402 and the credit checker block 404, but using the processing result of the command processing block 406, such as the device access-credit 420, the further access-credit 422, the credit exhaustion status 424, or a combination thereof.

The command completion block 408 is configured to finish the processing of the processing request 112. The command completion block 408 can finish by communicating the processing result 114 to the requesting host 316 that generated the processing request 112. The command completion block 408 can finish through completion posting.

The command completion block 408 can further return one or more credits. The command completion block 408 can return the one or more credits by returning the instance budget 410, the further budget 412, or a combination thereof to the credit checker block 404. The command completion block 408 can further return the credit by resetting the instance budget 410, the further budget 412, or a combination thereof.

The command completion block 408 can further pass or communicate the credit exhaustion status 424, the balance, or a combination thereof to the corresponding instance of the requesting host 316. The requesting host 316 can adjust a subsequent instance of the processing request 112 or any other processes therein based on the credit exhaustion status 424, the balance, or a combination thereof from the data provider 116.

It has been discovered that the processing request 112 based on communication direct from the data provider 116, such as the budget, the balance, the credit exhaustion status 424, or a combination thereof, provides increased overall efficiency. The direct feedback from the data provider 116 can be used to adjust the processes at each host via feedback, adjusting the processes from the host via budgeting. The direct feedback regarding the capacity of the data provider 116 along with other hosts can provide insight unavailable from blind systems or where the feedback is generated by the intermediate network component 108. The insight can be used to adjust for overall efficiency, which can further translate to increased efficiency for each device over time.

The credit checker block 404 can calculate the budget for the processing resource 124 and implement command count credit. The data provider 116 can use the command count credit to limit or control the number of individual commands serviced or carried out by the data provider 116 at any given point in time. Once this limit is reached or the credit is exhausted, the data provider 116 can stop further command fetching and processing.

The data provider 116 can begin at the beginning of the entity list and processes as many PCIe commands for that entity as its command count credit allows or host submits prior to the device fetch cycling. The data provider 116 can then move to the next entity on the next list entry to process as many PCIe commands for that entity as its command count credit allows. The data provider 116 can continue the above process until the data provider 116 reaches the end of the list. The data provider 116 can then repeat.

The credit checker block 404 can calculate the budget for the data resource 122 and implement data-transfer bandwidth credits for providing a way for the data provider 116 to limit the number of bytes transferred for a function or group functions, or to entire hosts, applications, or devices, according to corresponding groupings thereof. The limit can be imposed before beginning to process command transfers for other functions or groups of functions competing for transfer bandwidth transfer capacity.

The data provider 116 can begin at the beginning of the entity list and transfers as much data for that entity as its transfer bandwidth credit allows or host submits, prior to the device fetch cycle, before suspending transfer operations for that transfer command. The data provider 116 can then move to the next entity on the entity list to transfer as many bytes for that entity as its transfer bandwidth credit allows. The data provider 116 can repeat this process until the device reaches the end of the list. The data provider 116 can then repeat.

The instance budget 410, the further budget 412, or a combination thereof results in a physical transformation in the physical world, such as a physical change in the information communicated between devices, and utilized at and communicated through the requesting host 316. Movement in the physical world results in updates to the consumption prediction 418 or future demands, which can be fed back into the computing system 100 and generate subsequent instances of the instance budget 410, the further budget 412, or a combination thereof.

The computing system 100 has been described with module functions or orders as an example. The computing system 100 can partition the modules differently or order the modules differently. For example, the command processing block 406 and the command completion block 408 can be merged. Also for example, the credit checker block 404 can initiate by calculating the budget, the command fetch block 402 can then fetch the processing request 112 based on the budget.

Also for example, the command completion block 408 can return the credit or the budget back to the credit checker block 404. Also for example, the command fetch block 402 can track the usage or the balance.

As an illustrative example, the computing system 100 can implement an iterative scheme for the control flow. The control flow can be exchanged between the command fetch block 402 and the credit checker block 404 for the iterative scheme. The control flow can iteratively exchange between the command fetch block 402 and the credit checker block 404 to identify and interface with hosts and the manage the overall resources 120 according to the hosts.

Continuing with the illustrative example, the control flow can pass from the credit checker block 404 to the command processing block 406 as discussed above. The control flow can pass to the command processing block based on meeting a threshold condition, such as processing for or accounting for the all known or identified instances of the hosts. The control flow can be exchanged between the credit checker block 404 and the command processing block 406 for the iterative scheme.

Continuing with the illustrative example, the control flow can iteratively exchange between the credit checker block 404 and the command processing block 406 to process one or more requests or a portion therein corresponding to one or more hosts. The control flow can pass from the command processing block 406 to the command completion block 408 as discussed above. The control flow can pass based on meeting a threshold condition, such as generating a result or completing an internal process corresponding to the request.

Continuing with the illustrative example, the control flow can pass from the command completion block 408 to the credit checker block 404 as described above. The command completion block 408 can communicate with the hosts for providing results or notification purposes. The credit checker block 404 can process or update the credits as described above and reinitiate with the iterative mechanism.
